Esocidae.âMargin of the upper jaw formed by the praemaxillaries and maxillaries, the latter behind the former, and toothless. Supraoccipital in contact with the frontals, separating the small parietals ; opercular bones all well developed; basis cranii simple. No parapophyses, except to the hindermost prae- caudal vertebrae; epipleurals and epineurals. Post-temporal forked, the upper branch attached to the epiotic, the lower to the exoccipital; post-clavicle present. Vertical fins far back; no adipose dorsal fin. Pectoral fins inserted very low down ; ventrals with 6 to 11 rays. Air-bladder present. As in the Haplochitonidae, the neural and haemal arches are bones distinct from the centra, and although parapophyses are not developed, the ribs are not inserted on the centra, but on distinct bases wedged into the latter.^ Teeth are present on the vomer, palatine, and pharyngeal ^ ^ ^ Fig. 368.âSkeleton of £502; Zjici«s. (After Jordan and Evermann.) A small family of carnivorous freshwater Fishes, including the Pike [Esox], of predaceous habits, unsurpassed in greediness and voracity, and the small and insignificant-looking Umbra, distin- guished by the more anterior position of the dorsal fin, the larger scales,, and the moderately large gape, with feeble villiform teeth. The range of the Esocidae is restricted to the cold and temperate parts of the northern hemisphere. Besides the well-known Esox lucius of Europe, Northern â Asia, and the northern parts of North America, growing to a length of 4 feet, and the Maskinongy (E. nobilior) of north-eastern North America, reaching twice that length, the first genus comprises three smaller species from the Eastern United States. Eemains of Esox have been found in ' Forming, with the bases of the neurapophyses, the cross-shaped arran
